The "drafting tool set" is a "Dietzgen Commander Drawing Instruments" set.
While looking for additional information on this particular set, I found that
Dietzgen is still in business today, although no longer seems to sell this
particular product line. I was surprised to find that like-new versions of
this set can be had on eBay for less than $20, or for as low as $5 if you don't
mind if it's "missing 3 pieces."

The sign in the desk drawer reads

Dietzgen Drafting Tool Set
On loan from Dr. Margit von Braun
